Day Kimball Healthcare, which operates Day Kimball Hospital, will restrict hiring and implement employee furlough days in response to state cuts in hospital reimbursements, officials said on Thursday.

Robert Smanik, the health care group’s president and chief executive officer, said the “mitigation plan” will go into effect immediately.

“Since December, when Gov. (Dannel) Malloy’s office announced the cut backs in hospital reimbursements, the management team and board of directors of Day Kimball Healthcare have been scrutinizing our operating budget to develop a plan to offset the expected lost revenue while maintaining our high quality of care,” Smanik said.

He said the state budget cuts in December led to a $3.8 million “negative impact” to the group’s 2013 budget. Smanik said the group is also experiencing lower-than-expected volume in some of its operating divisions, while also incurring higher expenses, including heath insurance costs.

The mitigation plan calls for restricting hiring for all non-essential positions and re-aligning the responsibilities of some workers.

“Those positions that directly affect patient care will still be filled as needed,” said Sara Brandon, the group’s vice president of marketing and communication.

Brandon said employees in certain management positions will be required to take work furloughs, or unpaid days off.

“Senior management and directors will have to take three days off between now and Sept. 29,” she said. “There will be voluntary dates for the rest of our salaried employees.”

Brandon said the group’s physicians have agreed to open up extra slots on their calendars at no increased charge to see patients, a move which is expected to add to the group’s revenue stream.

The group will also eliminate integrative medicine services, including massage, stress management and acupuncture and will lose its sports management practice.

Under the governor’s two-year, $43.8 billion budget, funding for the treatment of uninsured and under-insured patients will be halved during the first year of the budget, and eliminated by July 1, 2015.

The plan cuts $207 million from the $1.58 billion that Connecticut hospitals receive this fiscal year, and comes on the heels of a deficit mitigation plan that cuts an uncompensated care patient fund by 25 percent.

The changes are related to the introduction of the federal Affordable Care Act, scheduled to begin Jan. 1 and to be completely implemented by 2016.

Under the new health care reform law, officials said those patients affected by the most recent changes would be insured — a prime impetus for the proposed hospital cuts.
